Title: Jointing plastics materials
Inventor: WAY KENNETH RICHARD
IPC: B29C65/02
Filed: 1964-02-13
Abstract: 1,037,966. Seaming non-metallic sheet material; moulding plastic substances. STANDARD TELEPHONES & CABLES Ltd. Feb. 13, 1964, No. 6099/64. Addition to 986,649. Headings B5A and B5K. [Also in Division H2] The cable jointing method described in the parent Specification in which the molten inner surface of a plastic sleeving and the molten outer surface of a plastic cable insulation are agitated by a member between them is modified by replacing the member by a plunger 42, which agitates the molten plastic by passing through the molten sheath 3 to the molten surface layer of the insulation and moving annularly round the cable. The plunger is forced through the layer by spring 43 and then scrapes the surface of the insulation as the whole apparatus (Fig. 1, not shown) carrying the mould block 6 is rotated around the cable. After agitation a smaller plunger is fitted, which does not protrude out into the mould, and the mould block is pushed further over the sleeve to cause the molten plastic to take its final shape. The end face of the plunger is roughened (Fig. 7, not shown) and a passageway is provided in the plunger so that as it rotates molten plastic passes down the passageway to the exit 62 in the end of the plunger, both arrangements give better mixing of the plastic. To avoid having to replace the plunger by a smaller one the embodiment of (Fig. 4, not shown) may be used where a pin is provided to hold the plunger partially withdrawn.

Title: Method of and apparatus for the vaporisation of fuels for use in internal combustion engines
IPC: F02M21/10
Filed: 1923-03-02
Abstract: 198,992. Akt.-Ges. fur Patentverwertung. June 10, 1922, [Convention date]. No Patent granted (Sealing fee not paid). Thermally - actuated valves; fluid - actuated valves.-An automatic valve is provided for controlling the admission of light or heavy fuel mixture to a vaporizer, and regulating the heating of the heavy fuel mixture by varying the point of admission to an exhaust heated passage. As shown in Figs. 1 and 2, the air and mixture are heated in a spiral passage 18-22 leading to an induction pipe 33, and surrounding a pipe 23 provided with passages 35 for the exhaust gases. The casing containing the spiral passage is provided at one side with an extension containing (1) a passage 25 provided at the top with an air valve 28 and communicating through a port 19<1111> with the spiral passage 19, (2) cross passages containing light and heavy fuel nozzles 27, 26, and (3) a second passage containing a sleeve valve 24 and communicating with the spiral passage 19-22. At starting, air enters at 18, traverses the passage 19, which is closed at 30, passes through the port 19<1111> to the passage 25 and flows over the nozzle 27 and through ports 22<11> and 22<1111> in the valve 24 to the passage 22 and induction pipe 33. As the temperature of the exhaust rises, the valve 24 is rotated by a toothed rack 34 operated by a lever 32 connected to a piston 31 working in a tube 29 containing expansible material, to close the ports 22<11>, 22<1111>, and to open a port adjacent the heavy fuel nozzle 26, and a port leading to the passage 19. The air then flows over the nozzle 26 and through the passage 19-22. As the temperature of the exhaust increases, the valve 24 is further rotated to cut off in succession the passages 19-21, so that finally the heavy fuel mixture flows from the nozzle 26 through the valve 24 direct to the passage 22. The air valve 28, which is operated by the rack 34 conjointly with the valve 24, is opened as the temperature rises, to admit unheated air. In the modification shown in Fig. 5, the spiral passage is replaced by annular passages 41, 42, 43 connected by cross passages 44. 44<1>, the valve 37 and air valve being operated through a flexible member only when a definite temperature is reached. To effect this, the tube containing the expansible material, and which traverses the exhaust pipe 49, is provided with two spring-pressed pistons, the one actuating the flexible member being operated only after the other piston has been moved to an extent determined by an adjustable stop. In a further modification, the sleeve valve and air valve are operated by a flexible member 66, Fig. 9, attached to a pulley 61 mounted on a spindle 58 in a tube 56 heated by the exhaust. A smaller pulley 59, secured to the pulley 61, is connected by a flexible member 65 to a large pulley 60, which carries a smaller pulley 59 secured by a flexible member 64 to a fixed stop 63.

Title: Improvements in slow speed alternating current motor mechanisms
IPC: H02K7/14
Filed: 1930-02-25
Abstract: 349,467. Electric plant for lifts. MAYER, P., 644, 7th Street, San Diego, California, U.S.A. Feb. 25, 1930, No. 6251. [Class 78 (ii).] An elevator car is driven by the primary members of two induction motors A, B which have their secondary members on a common shaft, and their primary members 15 mounted for rotation. Ropes 7, 8 attached to the car pass over a sheave 1 on the primary member of the motor A, over intermediate sheaves 3, 4 and over a sheave 2 on the primary member of the motor B, to a counterweight 6. Each of the primary members 15 are wonnd to give two speeds, e.g. 900 and 1200 revolutions per minute, and when a switch 29 is in the central position, the 900 winding of each machine is connected to the supply and electromagnetically operated brakes 25 engage the primary members so that the rotor shaft runs at 900 revolutions per minute, but the car is stationary. When the switch 29 is moved to the left, the coil D of a switch 30 is energized, and the switch changes the windings of the machine A, the coils of the brakes 25 are energized, and the primary members of the machines A, B rotate at 150 revolutions per minute in opposite directions to drive the car. By moving the switch 29 to the right a switch 31 is energized and the rotation is reversed. The switches 30, 31 have a time delay action to ensure that the brakes are released before the connections to a motor are changed. When the switch 29 is moved from a running position to the neutral position both machines function as generators to bring the primary members to rest. A switch 33 is provided, which is closed before the switch 29 is moved to its neutral position, to maintain the brakes 25 released, so that when the primary members have come to rest, the switch 33 may be opened to apply the brakes 25. More than two sets of windings may be given to each machine with any corresponding speeds.

Title: Improvements in, or relating to, devices for controlling fluid pressures
IPC: F16K17/10
Filed: 1942-05-12
Abstract: 557,188. Relief valves. BELTON, C. M. D., and BOTT, H. May 12, 1942, No. 6396. [Class 135] A pressure relieving device comprises a main valve actuated by a diaphagm under the control of a diaphragm-actuated relay valve itself controlled by a presure-actuated weight-loaded control valve. The main valve 27 is formed with a pocket 36 adapted to receive a part-spherical head 35 on a spindle 34 secured to a diaphragm 8. This diaphragm is subject on one side to the pressure in the main inlet 9 and on the other side to the pressure in a chamber 7 connected to atmosphere through restricted passages 15 and to the main inlet through pipes 13, 14 controlled by the relay valve 24. This valve is guided by a spindle 40 with flats 43 engaging a bore 42 and is carried by a diaphragm 4 loaded by a dead weight 23. Fluid from the main inlet acts on the underside of the diaphragm and is supplied to a chamber 2 above the diaphragm through a pipe 11 fitted with a restriction 12 and is exhausted when the pressure is sufficient to lift a weightloaded valve 17, through passage 42 and atmosphere vents 19. The diaphragm is lifted to open the valve 24 and admit pressure to the chamber 7 either by a sudden increase of pressure below the diaphragm or by venting the chamber above. The admission of pressure to the chamber 7 balances the pressures acting on the diaphragm and permits conduit pressure to open the valve 27 and allow the escape of fluid to reduce the conduit pressure to the desired value. The valve 27 is loaded by a spring 28 bearing against a bridge 29 which also carries an adjustable stop 30 for limiting the lift of the valve.

Filed: 1927-03-08
Abstract: 281,908. Whitby, H. March 8, 1927. Springs, arrangement of; equalizing load on springs and wheels.-In a rigid-framed motor vehicle having six or more wheels and supported directly on the axle springs of the rear sets of wheels, certain of the wheels are adapted to move laterally of the frame in co-ordinated relationship with certain other wheels which are also laterally movable, so that the wheels having such co-ordinated movements may position themselves partially or completely in an automatic manner when steering or turning movements of the vehicles are being effected. In the arrangement shown in Fig. 1, the adjacent ends of the springs 14, 17 of the rear axles 3, 2 of a six-wheeled rigid frame vehicle are connected to shackles 13, 16 mounted on vertical pivots in the ends of a shackle plate 8 which is free to slide longitudinally and turn in a horizontal plane in a housing 6 pivotally mounted on the end of a bar 1 on the frame. The other ends of the springs are connected to shackles 20 which slide and rotate on vertical pivots in brackets 22, 26 on the frame. When the vehicle is turned, relative movement between the rear end of the frame and rear wheels causes the springs 14 to swing laterally about the shacks 20. and the connection between the springs 14, 17, causes the springs 17 to swing in the opposite direction about the shackles 24. In the modified arrangement shown in Fig. 3, the adjacent ends of the springs 14, 17 are free to move longitudinally and transversely in a housing 29 pivoted on the bar 1, the rear ends of the springs 14 being mounted on transverse pivots 20 on a bar 50 free to move longitudinally and transversely on the frame, while the front ends of the springs 17 are connected to shackles 24 pivoted on vertical axes on brackets 26. The axles are interconnected by arms 31, 35 and a link 34, the arm 31 being pivoted at 32 to the frame. The axles may have arms connected by a link pivoted between its ends to the frame so that the adjacent ends of the springs are swung in opposite directions. In a modified arrangement similar to Fig. 1, the leading rear axle is centrally pivoted to the frame and the front ends of the springs 17 are connected to a cross-bar movable transversely of the frame and having a spring-controlled pin and slot connection with a lever connected to the steering mechanism so that the automatic positioning of the wheels is initiated by the steering mechanism, thus facilitating steering when turning sharply or driving in reverse. The shackle plates may also be universally mounted in their housings in any suitable manner. In a further modification of the arrangement shown in Fig. 1, the front ends of the springs 17 are connected to a cross bar centrally pivoted to the frame.

Abstract: 854,174. Protective arrangements. GANZ KAPCSOLOK ES KESZULEKEK GYARA. Feb. 28, 1957, No. 6755/57. Class 38 (5). [Also in Group XI] A thermal image for an electric motor comprises a temperaturesensing element, e.g. a thermometer 1 heated by a resistance coil 2 having spaced around it a second heating coil 4 and between them a metal shell 5 forming a heat accumulator. The coils 2, 4 may be individually energized or connected in series or parallel. The thermometer 1 is chosen to have a temperature-time characteristic substantially the same as that of the motor so that when the motor is in cooler surroundings it can be overloaded. The thermometer carries one or more contacts, so that on rise of temperature, a lower contact operates a signal, e.g. a bell and an upper one operates a relay to cut off current to the motor. A cylinder 6 of heat-insulating material surrounds the outer coil 4 when the device is to simulate a stationary motor, and this cylinder may be displaced when the device is to simulate a rotating motor, e.g. by an electromagnet operated by the motor current; or the cylinder 6 is stationary and ventilating flaps 7 in an outer casing are opened when the motor is running. The coils 2, 4 are energized from a transformer, the inner coil 2 being mainly effective during rapid heating and the outer coil 4 being supplied according to the cooling of the motor. A third heating coil may be used where iron induction heating of the motor is high or where the device is mounted in a cooler atmosphere than in the space around the motor. The metal shell 5 may be iron and may be inserted to a variable extent between the coils; and interchangeable shells of different thickness or heat capacity may be used in accordance with the heating time constant of the motor. Two transformers for the coils may be used ; and a motor protective device preferably comprises two 2- phase protecting mercury thermometers with a glow lamp indicating voltage across a relay. A cover-plate 3 regulates ventilation adjacent the inner coil 2, which may be carried on a support having a heat capacity chosen according to the motor to be protected. A maximum-minimum thermometer may be used.
